Maintenance Operation  

a. Ensure that the power supply conditions match the operational requirements of the oil cooler.

b. The oil cooler is compatible with hydraulic oils of grade 5 or 68. If you are using oil with a grade higher than 68, check whether the oil cooler is compatible and consult the manufacturer if necessary.

c. Periodically check the oil level in the tank. The oil cooler should not run with low or no oil. If you find any issues with the oil flow or pump, identify the problem and resolve it before resuming operation.

d. Regularly inspect the oil filter mesh and clean it as needed.

e. Ensure that the air inlet/outlet of the oil cooler is not obstructed, and that the spacing meets operational requirements.

f. At least once a week, check the surface of the fin-type condenser filter mesh. If you observe dust or oil stains, remove the filter mesh and wash it with cold/warm water. For oil stains, use a detergent. Dry the filter mesh before putting it back in place. Use a brush or compressed air to remove excess dust from the condenser fins.

g. If the oil cooler has been idle for a long time or has been in use for an extended period (about six months), check the condenser fins for blockage by dust or other particles.

h. Constantly monitor the operation of the oil pump and motor. If you notice abnormal noise or high temperature, immediately halt the operation and either inspect the oil circuit system or consult the manufacturer.

i. Regularly check the insulation properties of the compressor, fans, and oil pump to ensure reliable usage.

j. Depending on the oil quality within the tank, conduct a comprehensive inspection and cleaning of the oil circuit system every 3-6 months.

k. The optimal operating temperature range for the oil circulating in the oil cooler is 25~50°C. Below 25°C, the oil viscosity increases, reducing the cooler's efficiency.

l. If the oil temperature exceeds 55-60°C, check whether the machine is operational, whether there are any faults, whether the cooling filter mesh is blocked, or if the ambient temperature is too high, thereby reducing cooling efficiency.

m. The working environmental temperature for the unit is -5~35°C. Above 40°C, the cooling efficiency of the oil cooler decreases, so immediate action should be taken to improve the environment.

n. If the surface of the oil cooler is dirty, wipe it with a soft cloth dampened with a neutral detergent or soap.

o. Always disconnect the power supply during routine maintenance and inspection.
